RICHMOND—Pro Bowl left tackle Trent Williams did not practice Friday, presumably due to the minor leg injury he suffered a day earlier.

Coach Jay Gruden said Thursday that Williams had been inadvertently kicked in the shin during that day’s practice. Gruden also said the injury is not serious, and the fact that Williams watched Friday's session from the sidelines seems to confirm that notion.

Here are the other injury updates from the Bon Secours Training Center:

Wide receiver Jerry Rice Jr. injured his shoulder Thursday and was not on the field Friday morning. Gruden said the team fears the injury is significant and the rookie tweeted, “Really unfortunate situation. Just gotta take the steps needed to recover as fast as possible … Got to trust the plan for me.”

Wide receiver Pierre Garçon returned to practice after sitting out two days with a hamstring strain. He was a full participant.

Safety Phillip Thomas (hamstring) took part in individual work but watched from the sideline during team drills.

The Redskins practiced in shells, not shoulder pads as Gruden had said they would. It was not immediately clear if the decision was influenced by the team's collective health, the morning rain or both.
